CLOSURE OR STOPPER FOR VESSELS.

SECIFICATION forming part of Letters Patent No..641,806, dated January23, 1900.

Application filed Oeto'ber 25, 1899.

for bottles, jars, and other vessels, more esf pecially a stopper formilk and cream bottles, i' and has for its object to provide a stoppersimple and inexpensive in construction which is adapted to be firmlyretained in the neck of the bottle against accidental displacement andcan be easily removed when desired to allow a portion of the contentsthereof to be discharged and then be replaced, so as to preserve theremainder of the contents, and also to serve as a cup to catch andretain any dirt or other foreign matter and prevent it from falling intothe milk when the stopper is being removed.

My invention consists of a cup-shaped stopper for vessels, having aspring-acting rim and a tab; audit further consists in the construction,combination, and arrangement of parts more fully hereinafter describedand claimed.

My invention is illustrated in the accompanying drawings, Yin .Which-Figure l is a sectional view of a portion of a bottle, showing mystopper in place therein;

Fig. 2, aperspective view of the stopper; Fig.

3, a similar view of a modification thereof. Fig. 4 is a sectional Viewof aportion of a bottle provided with a shoulder and showing my stopperin place therein.

In the accompanying drawings, in which like letters of reference denotelike parts, A is a bottle having a circumferential groove B in its neck.C designates my improved stop per inserted therein and consisting of acupshaped body portion having an annularspring acting rim D, providedwith cut-away portions or slits E, and a tab F, projecting from theupper edge thereof, said spring-acting rim adapted to be compressed bythe walls of the neck of the bottle as the stopper is being pressed intoplace in the groove therein and Serial N0. 734,767. (No model.)

when seated to spring out and engage said groove.

It will be seen that by having the tab eX- tend vertically from theupper edge of the rim of the stopper when it is pulled upward to removethe stopper there will be no tendency to tear the same from the rim, aswould be the case if the tab were at an angle thereto.

The stopper is preferably made of paper and stamped into shape; but itmay be made of any other suitable material and shaped by any othersuitable means.

To insert the stopper, take hold of the tab and force the stopper intothe neck of the bottle until the spring-acting rim engages the kgroovetherein, when it will be held securely in place. When it is desired toremove the stopper, take hold of the tab and pull it upi ward. This willcompress the spring-acting rim and allow the stopper to be removed.

Although in Fig. l of the drawings I have shown my stopper applied to abottle provided with a groove in its neck, it is equally applicable to abottle provided with a shoulder instead of a groove, as shown in Fig. 4,and in this case the stopper is inserted by forcing it into the neck ofthe bottle until it seats itself on the shoulder, when the springactingrim will press against the walls of the neck of the bottle, and thushold the stopper securely in place.

I-Iaving thus described my invention, what I claim isl. A stopper forvessels comprising a cupshaped body portion providedwith a tabprojecting from an upright rim thereof, substantially as described.

2. A stopper for vessels comprising a cupshaped body portion having anupright rim which is cut away and slitted at several points and providedwith a tab projecting from the said rim substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
